[ccp4bb] Cryo-protectant

[Liew Chong Wai]

Hi all, 
 
Good day
I used MPD as a cryoprotectant (20%, 30%) for my crystal. However, there is no 
diffraction signal at all. Without the MPD cryo, i still manage to get 
5angstrom, but it has very strong ice-ring signal. I used glycerol (15%, 20%, 
25% and 30%) before, but it cracked the crystal. 
 
Please advice.
 
Thanks
